Server creation fails when the JRE name differs from the oomph default

[Zuplyx]

When the name of a JDK differs from the oomph default of "JRE for JavaSE-$version" the server installation fails.

This is reproducible by the following snippet which creates a JDK named "JDK11" and uses it for Tomcat creation:

<setupTask
        xsi:type="jdt:JRETask"
        id="jre11"
        version="JavaSE-11"
        location="${jre.location-11}"
        name="JDK11"/>
        
<setupTask
          xsi:type="server:TomcatServerTask"
          id="tomcat9"
          serverName="Tomcat v9.0 Server at localhost"
          location="${installation.location}/apache-tomcat-9.0.37"
          runtimeName="Apache Tomcat v9.0"
          startTimeout="45"
          stopTimeout="15"
          jreVersion="${jre11.version}"
          serverVersion="Tomcat 9.0">
<description>Tomcat 9.0 server configuration</description>
</setupTask>

This leads to the following exception:
